The Liebert TYPE SS Type I Model
offers a true, coordinated multi-stage
system of suppression. It integrates
the fast response time of the silicon
avalanche diode (SAD) with the highenergy capability of the metal oxide
varistor (MOV) for increased reliability
and performance. This unique circuitry
30000 does not sacrifice the sensitive SAD
module when subjected to a
damaging high-energy transient event.
